Professor

## Sungjin Kim

**Most Helpful Review**

Professor Kim's class is very organized and clear. Even though he is not the best and most interesting math professor out there, his classes are easy to follow and he does a lot of practices and recaps. He writes all his explanations on the board (in a way that I think is even better than the textbook), so you actually only need the textbook for his homework problems. His homework problems can be a little challenging, but they are still reasonable. The two midterms were very easy for me, while the final is a lot more challenging, but overall, if you do all his practices and review your homework and what he normally goes through in class (and keep a cool head during the exams), the class is not hard at all. He has a bit of an accent, but he can answer questions very well. I also went for office hours two days before the final and it was super helpful. I will recommend this professor to anybody.

I would try to avoid Kim if there are other options for math. His accent is hard to follow and he spends more time in class doing proofs and theorems then on explaining the material. I watched Kahn academy videos every night before lecture so that I would be able to follow him in class. He also teaches in a confusing manner so watching Kahn academy videos helped simplified what he was trying to say.

Had him for both 31B and 32A. Pretty good professor overall. He lectures clearly and is easy to follow. His office hour is super helpful since he is always willing to show you the answer in homework(which is closely related to the exams), and present some methods that can be used to solve problems in the exam. Be sure to do his practice exams!!!!! Got A's in both classes.

Lectures He made his class easy to take because he sent out his lecture notes beforehand and also did Bruincast. His lectures were useful when you looked at the notes afterwards for help on the homework. He did a fair number of examples in class. The material itself is not difficult. Having received a C+ in Math 31AB, the new material here was easier to digest. There is some multivariable stuff involving limits, so you should be careful there. Grading Schemes Scheme 1 Homework 15% Midterm 1 20% Midterm 2 20% Final 45% Scheme 2 Homework 15% Better Midterm 30% Final 55% Homework His homework load was fair (~10 problems per week) and the grader chose three easy problems to correct. If you somehow messed up, he would drop the lowest homework score. Exams They were easy. Unlike other professors, he didn't try to trick you with ridiculous functions and whatnot. I got 100% on the first midterm, 88% on the second, and 80% on the final. The medians were 93%, 83%, and 80%, respectively. Unfortunately, I ended with an 89% and received a B+. The class was too easy, so there was a traditional grading scale and no curve. Office Hours He had two office hours per week, but I only went once. He was nice about my question, but I preferred to attend my TA's office hours. Pro-Tip The only thing you need to study for exams are his practice exams. They are basically the same as his actual exams; don't bother with anything else he suggests that you study. For example, he taught Kepler's laws, but didn't test on them. I was paranoid about the final because I thought he would throw a curveball, so I studied some other things and didn't spend as much time on the practice final. The actual final was basically the same as his practice one. Cue my regrets. tl;dr Take him for 32A, but make sure you are on top of his practice exams.

Professor Kim is a very professional instructor. His lecture is very organized and easy to follow. By using enough examples, the concept he taught are easy to be grasped. He replies the emails on time and gives a lot of hint on his homework. Most importantly, he provides practice exam and study guide for midterm and finals which are extremely helpful. As a student in UCLA, I do feel flattered to have a math professor who provides study guide and a whole lecture for review without any students ask for it! Overall, he is a good professor and I would not mind to choose him again if possible.
